Kinetic Energy

Rocking out in the iRock Rocking Chair recharges a connected iDevice and powers the chair'...

We’ve seen plenty of iPhone and iPad chargers that harness power from eco-friendly sources such as wind and solar (or both), but Zurich-based Micasa Lab has turned to a different, relatively (but not completely) untapped energy source to keep the juice flowing in iOS devices – the rocking chair. But the iRock Rocking Chair doesn’t just use the power generated via rocking back and forth to charge iOS devices, it also powers speakers built into the chair’s backrest.  Read More

The Kickstart uses kinetic energy to help improve the gait of people who have difficulty w...

Like Honda’s Stride Walking Assist and the ReWalk, the Kickstart from Cadence Biomedical is designed to help improve the gait of people who have difficulty walking and help them regain their mobility and independence. But unlike its robotic cousins that are powered by weighty rechargeable batteries, the Kickstart is able to ditch the batteries altogether because it has no motors to power. Instead, it is purely mechanical and provides assistance by storing and releasing kinetic energy generated by a person when walking.  Read More

Jupiter is a major player in protecting the Earth from impact events, and has been for billions of years. Between comets and asteroids impacting on Jupiter and being flung into the Sun or out of the Solar System entirely, Jupiter's enormous gravitational field has removed the greater proportion of debris left-over from the formation of the Solar System. Jupiter has again been caught in the act of attracting and eating dangerous space rocks—this time in simultaneous observations by two amateur astronomers.  Read More

EcoXPower converts pedal-power into electricity for both headlights and a smartphone

EcoXPower by EcoXGear is another take on a concept which most Gizmag readers will be familiar with: harnessing the kinetic energy produced while one pedals a bicycle in order to convert it into electricity and charge a smartphone or similar device. Though we’ve covered several products of this nature in the past, such as Nokia's Bicycle Charger Kit, Dahon's BioLogic ReeCharge, and the PedalPower+, the EcoXPower sets itself apart by charging your smartphone or GPS and providing electricity to front and rear lights at the same time.  Read More

Charge music players, phones and other portable devices with your legs

K-TOR has added a new portable charging device to its lineup. The new Power Box puts your legs to work toward converting kinetic energy to electricity. Use it enough and you might just get your weekly workout. It is quite simply a pedal-powered generator equipped with a dual-pronged outlet so that you can plug in an AC adapter and charge your device directly from your leg power. The box works for devices rated 20W and below, including low-power netbooks, tablets, smartphones, video devices and portable game systems.  Read More

Last month U.S. Military, government and industry officials witnessed a demonstration of a new missile warhead casing material at the Naval Surface Warfare Center (NSWC) in Dahlgren, Virginia. The material, known as High-Density Reactive Material (HDRM), is the result of collaboration between the Office of Naval Research (ONR), NSWC Dahlgren and NSWC Indian Head Divisioncan and can be employed within existing designs, but with added destructive power.  Read More

Mazda claims its new i-ELOOP system is the first passenger vehicle regenerative braking sy...

While Toyota took out the Tokachi 24-Hour Race in 2007 with a Supra HV-R hybrid race car featuring a quick-charging supercapacitor-based regenerative braking system, battery storage has so far been the norm for these systems in production vehicles. Now Mazda is charging things up with its new "i-ELOOP" system intended for internal combustion engine-powered vehicles. The i-ELOOP is billed as the world's first passenger vehicle regenerative braking system that uses a capacitor in place of rechargeable batteries to temporarily store energy captured from braking.  Read More

An artist's impression of the GBU-57A/B

Military technology has created some fearsome weapons, such as the 5,000 lb GBU-28 Deep Throat bunker buster, 15,000 lb BLU-82 Daisycutter, 15,650 lb Russian ATBIP (Aviation Thermobaric Bomb of Increased Power), 22,000 lb Grand Slam earthquake bomb, and the 22,600 lb GBU-43 MOAB (Massive Ordnance Air Blast), but if you were hiding under 50 meters of hardened concrete, none of them were going to bother you. Not any more! The U.S. Air Force has just taken delivery of the first GBU-57A/B (Massive Ordnance Penetrator). It weighs 30,000 lb and will penetrate 200 ft of hardened concrete BEFORE it goes off. If you are reading this from an underground nuclear facility in Iran or North Korea, might we suggest some extended sick leave is (or soon will be) in order.  Read More

Pavegen tiles harvest kinetic energy from pedestrian traffic

Can you imagine the power of 50,000 steps a day? Well, Laurence Kembell-Cook, the director of Pavegen Systems imagined it and created Pavegen tiles - a low carbon solution that aims to bring kinetic energy harvesting to the streets. Not surprisingly, the tile is receiving a great deal of attention as a solution for power-hungry cities with a lot of walking traffic.  Read More

The Flybus consortium is set to start testing its prototype flywheel hybrid bus

Gas/electric hybrid vehicles tend to be pricier than their conventional counterparts, and many people still worry about the limited range of all-electrics. If you want to move away from purely petrol-powered vehicles, though, is there any alternative? The four-company Flybus consortium would definitely say there is. It recently rigged up a bus with a prototype flywheel-based energy recover system, that stores the energy that would be wasted when the vehicle brakes, then returns that energy to the drivetrain when the bus accelerates. The researchers claim that it could deliver hybrid-like fuel economy, at a fraction of the price.  Read More
